/*
* Modelling file for Coverity Scan
*
* This is a modeling file for Coverity Scan. Modeling helps to avoid false
* positives.
*
* - A model file can't import any header files.
* - Therefore only some built-in primitives like int, char and void are
* available but not NULL etc.
* - Modeling doesn't need full structs and typedefs. Rudimentary structs
* and similar types are sufficient.
* - An uninitialized local pointer is not an error. It signifies that the
* variable could be either NULL or have some data.
*
* Coverity Scan doesn't pick up modifications automatically. The model file
* must be uploaded by an admin.
*
* See also https://scan.coverity.com/models
